1. The graph of f (x)=cos(x) is transformed to a new function, g(x), by stretching it horizontally by a factor of 4 and shifting it 1 unit up.
What is the equation of the new function g (x)?
What is the amplitude of the function f(x)?
What is the equation of the midline for the function f(x)?
I really appreciate your help. Thanks so much.
